Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a tensioning mechanism of a labeling machine. Background Art

[0002] Label printers are often used in automated production lines to attach labels to items on the production line for subsequent packaging. Most label printers use roll-fed thermal label paper. During use, the roll-fed thermal label paper goes through the processes of unwinding, printing by the printer, and rewinding of the backing paper. During this process, the tension of the label paper needs to be adjusted to stably output the printed labels. However, the tension of existing label printers is not easy to adjust, and situations such as label paper jamming or two label papers being continuously output are likely to occur, resulting in malfunctions.

[0003] In the prior art, patent number (CN202220825340.8) mentions a label printer tensioning mechanism including a fixing plate, a printer assembly, and a tensioning assembly; the printer assembly is arranged on one side of the fixing plate, and the tensioning assembly is arranged on the other side of the fixing plate; the printer assembly includes a printer, an unwinding shaft, a rewinding shaft, a first tensioning shaft, a second tensioning shaft, and a third tensioning shaft. The printer is provided with a label support plate. Through the cooperation of the counterweight block, the sensing flap, and the first distance sensor of the tensioning assembly, after a single label paper is printed, the backing paper of the label paper will be in a loose state. Under the gravity of the counterweight block, the counterweight block drives the counterweight disc to rotate, further driving the sensing flap to rotate synchronously. By adjusting the relative position relationship between the first distance sensor and the sensing flap, the rewinding force of the rewinding shaft is kept consistent, preventing printer malfunctions caused by excessive or insufficient rewinding force.

[0004] In the prior art, the addition of the sensing flap and the first distance sensor effectively solves the problem that the tension of existing label printers is not easy to adjust, and situations such as label paper jamming or two label papers being continuously output are likely to occur, resulting in malfunctions. However, since the overall optimization and modification mainly focus on the label printer itself, and the tensioning mechanism is hardly optimized, when parts in the label printer are damaged, the tensioning mechanism will be unable to perform effective discharging control operations. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tensioning mechanism of a labeling machine, which solves the problem that since the traditional labeling machine is mainly optimized and modified for the labeling machine itself, and the tensioning mechanism is hardly structurally optimized, when parts in the labeling machine are damaged, the tensioning mechanism will be unable to perform effective discharging control operations.

[0006] To achieve the above object, a tensioning mechanism of a labeling machine adopted by the present utility model includes side plates and an adaptive control tensioning assembly. The adaptive control tensioning assembly further includes a protective pad, a control wheel, and a rotating seat. The protective pad is detachably connected to the side plates and is located on one side of the side plates. The control wheel is detachably connected to the protective pad and is located on the side of the protective pad away from the side plates. The rotating seat is rotatably connected to the control wheel and is located on the side of the control wheel away from the protective pad.

[0007] Wherein, the adaptive control tensioning assembly further includes a top plate and control teeth. The top plate is detachably connected to the side plates and is located above the side plates. The control teeth are fixedly connected to the control wheel and are located on the outer surface of the control wheel.

[0008] Wherein, the adaptive control tensioning assembly further includes a connecting rod and a rotating shaft. The connecting rod is rotatably connected to the rotating seat and is located on the side of the rotating seat away from the control wheel. The rotating shaft is rotatably connected to the connecting rod and is located on the side of the connecting rod away from the rotating seat.

[0009] Wherein, the adaptive control tensioning assembly further includes a transmission roller and a recovery roller. The transmission roller is arranged on the outer surface of the rotating shaft. The recovery roller is rotatably connected to the side plates and is located on the side of the side plates close to the protective pad. And the recovery roller is arranged below the protective pad and is arranged on the same horizontal line as the rotating shaft.

[0010] Wherein, the transmission roller is in a hollow elliptical shape, and the recovery roller is in a cylindrical shape.

[0011] Wherein, the tensioning mechanism of the labeling machine further includes a connection and installation assembly. The connection and installation assembly includes a positioning groove, a placement block, and an installation groove. The positioning groove is detachably connected to the side plates and is located on one inner side of the side plates. And the positioning groove is perpendicular to the protective pad. The placement block is detachably connected to the side plates and is located inside the side plates. And the placement block is arranged inside the positioning groove. The installation groove is fixedly connected to the side plates and is located inside the side plates. And the installation groove is arranged on one side of the positioning groove.

[0012] The tensioning mechanism of a labeling machine of the present utility model includes side plates and an adaptive control tensioning component. The adaptive control tensioning component further includes a protective pad, a control wheel, and a rotating seat. The protective pad is detachably connected to the side plates and is located on one side of the side plates. The control wheel is detachably connected to the protective pad and is located on the side of the protective pad away from the side plates. The rotating seat is rotatably connected to the control wheel and is located on the side of the control wheel away from the protective pad. Since the traditional tensioning mechanism is replaced with an adaptive control tensioning component, it effectively solves the problem that the optimization and modification of the traditional labeling machine mainly focus on the labeling machine itself, while the tensioning mechanism hardly undergoes structural optimization. As a result, when parts in the labeling machine are damaged, the tensioning mechanism will be unable to perform effective discharging control operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] The first embodiment

[0021] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the overall structure of the first embodiment of the present utility model, Figure 2 which is a front view of the overall structure of the first embodiment of the present utility model, Figure 3 which is the present utility model Figure 2 and is an enlarged view of the partial structure at position A.

[0022] The present utility model provides a tensioning mechanism for a labeling machine, including side plates 101 and an adaptive control tensioning component. The adaptive control tensioning component further includes a protective pad 103, a control wheel 104, a rotating seat 106, a top plate 102, control teeth 105, a connecting rod 107, a rotating shaft 108, a transmission roller 109, and a recovery roller 110. Through the foregoing solution, the problem that since the optimization and modification of traditional labeling machines mainly focus on the labeling machines themselves, and the tensioning mechanism has hardly been structurally optimized, resulting in the inability to perform effective discharging control operations when parts in the labeling machine are damaged can be solved. It can be understood that in the foregoing solution, when performing labeling and discharging, the label can be placed between the transmission rollers 109, and then the control wheel 104 controls the rotation of the rotating seat 106, and the rotating seat 106 will effectively drive the connecting rod 107 and the rotating shaft 108 to rotate, thereby rotating the transmission roller 109. Since the transmission roller 109 is provided in a hollow elliptical shape and is made of rubber, it has good elasticity and ductility, and thus can effectively complete the discharging control operation within a certain error range. After the labeling operation is completed, the recovery roller 110 will recover the waste materials (label stickers) to prevent environmental pollution. Therefore, the problem that since the optimization and modification of traditional labeling machines mainly focus on the labeling machines themselves, and the tensioning mechanism has hardly been structurally optimized, resulting in the inability to perform effective discharging control operations when parts in the labeling machine are damaged can be effectively solved.

[0023] For this specific embodiment, the protective pad 103 is detachably connected to the side plate 101 and is located on one side of the side plate 101. The control wheel 104 is detachably connected to the protective pad 103 and is located on the side of the protective pad 103 away from the side plate 101. The rotating seat 106 is rotatably connected to the control wheel 104 and is located on the side of the control wheel 104 away from the protective pad 103. The protective pad 103 is the main auxiliary structural component for protecting the adaptive control tensioning component and the side plate 101, and the control wheel 104 will effectively cooperate with the control teeth 105 to directly control the number of rotation turns of the rotating seat 106, and the rotating seat 106 is the functional component for controlling the rotation of the connecting rod 107 and the rotating shaft 108.

[0024] Among them, the top plate 102 is detachably connected to the side plate 101 and is located above the side plate 101. The control tooth 105 is fixedly connected to the control wheel 104 and is located on the outer surface of the control wheel 104. The control tooth 105 is an auxiliary structural component that cooperates with the control wheel 104 to control the rotation of the rotating seat 106.

[0025] Secondly, the connecting rod 107 is rotatably connected to the rotating seat 106 and is located on the side of the rotating seat 106 away from the control wheel 104. The rotating shaft 108 is rotatably connected to the connecting rod 107 and is located on the side of the connecting rod 107 away from the rotating seat 106. The connecting rod 107 is a structural component connecting the rotating shaft 108 and the rotating seat 106, and the rotating shaft 108 is a structural component that transmits the rotational force to the transmission roller 109.

[0026] At the same time, the transmission roller 109 is arranged on the outer surface of the rotating shaft 108. The recovery roller 110 is rotatably connected to the side plate 101 and is located on the side of the side plate 101 close to the protection pad 103, and the recovery roller 110 is arranged below the protection pad 103, and the recovery roller 110 is arranged on the same horizontal line as the rotating shaft 108. The transmission roller 109 is the main functional component for controlling the discharge operation, and the recovery roller 110 is the main functional component for recovering the waste (label sticker) after the discharge marking is completed.

[0027] In addition, the transmission roller 109 is in a hollow oval shape, and the recovery roller 110 is in a cylindrical shape. Both the transmission roller 109 and the recovery roller 110 are made of rubber material. Therefore, both the transmission roller 109 and the recovery roller 110 have excellent elasticity and ductility, and thus can effectively control the discharge operation within a certain error.

[0028] When using the present utility model for label - punching and discharging, place the label between the transmission rollers 109. Then, the control wheel 104 controls the rotation of the rotating seat 106. The rotating seat 106 will effectively drive the connecting rod 107 and the rotating shaft 108 to rotate, thereby rotating the transmission rollers 109. Since the transmission rollers 109 are hollow - elliptical and made of rubber, they have good elasticity and ductility. Thus, the discharging control operation can be effectively completed within a certain error range. After the label - punching operation is completed, the waste material (label sticker) will be recycled by the recycling roller 110 to prevent environmental pollution. This effectively solves the problem that the optimization of the traditional label - punching machine mainly focuses on the label - punching machine itself, and the tensioning mechanism has hardly been structurally optimized. As a result, when parts in the label - punching machine are damaged, the tensioning mechanism cannot effectively perform the discharging control operation.

[0029] Second Embodiment

[0030] Please refer to Figure 4 , Figure 4 which is the rear view of the whole of the second embodiment of the present utility model.

[0031] Based on the first embodiment, the tensioning mechanism of a label - punching machine of the present utility model further includes a connection and installation component. The connection and installation component includes a positioning groove 201, a placement block 202, and an installation groove.

[0032] For this specific embodiment, the positioning groove 201 is detachably connected to the side plate 101 and is located on one side inside the side plate 101. The positioning groove 201 is perpendicular to the protective pad 103. The placement block 202 is detachably connected to the side plate 101 and is located inside the side plate 101. The placement block 202 is arranged inside the positioning groove 201. The installation groove is fixedly connected to the side plate 101 and is located inside the side plate 101. The installation groove is arranged on one side of the positioning groove 201. When it is necessary to replace the traditional tensioning mechanism in the label - punching machine, disassemble the original tensioning mechanism. Then, the placement block 202 in the positioning groove 201 is used for positioning to prevent deviation during installation and affect subsequent effects. Then, the installation groove is docked with the installation module of the label - punching machine, and thus the whole is installed on the label - punching machine for use. Compared with the traditional integral and bolt - connection methods, the snap - fit connection between the placement block 202 and the installation groove ensures a certain stability and is more convenient for disassembly and replacement.
